The comparison of this refit and the previous model results
(see Figs. REF -REF )
demonstrate the large impact of the new data on the analysis. A full account of the impact of the new data on nucleon
resonance parameters will be given in a journal paper. Here, we discuss as example only the helicity-3/2 contributions
of the lowest partial waves. The new fit results in the partial waves \(3/2^-\) , \(3/2^+\) , \(5/2^-\) , and \(5/2^+\)  are shown in
Fig. REF . Previous fits to the proton data [1]}, [2]} suggested that substantial
strength of the second nucleon resonance bump around \(W\) =1500 MeV comes from a sequential decay of the \(N(1520)3/2^-\) 
resonance via the \(\Delta (1232)\)  state (\(3/2-\)  wave). This is confirmed and an even more dominant contribution of this
partial wave is found for the neutron target. The \(3/2^+\)  wave has contributions from the \(N(1720)3/2^+\)  state.
However, it is also important in the threshold region where no resonance with this quantum numbers exists. The importance
of this wave at low energies was already noted in Ref. [3]}, but it is quantitatively improved by the
present data. The two-humped structure in Fig. REF  is mainly the result of interference of the \(N(1720)3/2^+\) 
resonance with a wide non-resonant background. There is, however, no clear understanding of the nature of the strong
background contribution. As discussed in Ref. [3]} at least part of it is related to the
\(\pi ^+\pi ^-\rightarrow \pi ^0\pi ^0\)  rescattering effect.
